Yes, I freely write quite a bit, at least that’s been the case in the past few months (I’ve written 27k words in my private journal since February 1st). When I write something like this essay, I know before I write it that it’s something I want to publish and I generally don’t start writing something that I’m going to publish unless the idea or point is so clear in my head that I can write it out and have it almost ready to go. I always go back and edit, but I rarely have to rewrite huge parts of the initial draft.
